Introduction
This information sheet gives advice to users on how
to use All Terrain Vehicles (ATVs) safely with towed
and mounted equipment.
Plan the use of an ATV carefully and take particular
note of ground conditions and slopes, as these may
vary considerably, depending on the terrain, weather
conditions, ground surface and the crop under the
wheels.
Towed equipment
Choose equipment which matches your ATV.
Stability of towed equipment is affected by:
Weight ratios
The safe ratio between the trailed laden maximum
weight and unladen weight of the ATV must be
assessed for each operation.
Always take note of information given in the
manufacturer’s handbook when making this
assessment.
As a guide research shows that on level ground, 4 x
unladen weight of the ATV for braked trailed
equipment and 2 x unladen weight of the ATV for
unbraked trailed equipment are the appropriate
maximum ratios.
Note: For work on slopes or uneven ground the ratio
will need to be reduced.
Braking
Fit:
Brakes to trailed equipment. This helps prevent jack-
knifing when braking or travelling downhill;
Over-run brakes which come into action whenever
the ATV brakes are applied;
Agriculture Sheet No 11
Centre of gravity
Stability of the ATV is improved if there is:
A low centre of gravity which is within the wheel
base;
A wide wheel base;
A long draw-bar;
Means for holding detachable equipment in position.
Hitching and loads
Stability is also improved if:
Some weight is transferred from the trailer onto the
ATV draw-bar;
The draw-bar has a swivel hitch and the ATV a ball
hitch having a large head to neck ratio. This makes it
easier for the draw-bar hitch to swivel and cope with
undulating ground;
The load is positioned as near to the centre of the
trailer as possible.
Tyres and wheels
Check tyre pressures regularly with a pressure
gauge capable of reading low pressures accurately;
Check tyre pressures regularly for damage and
wear;
Select equipment which has tyres and wheels that
can cope with speeds over 20 mph and occasional
higher speeds;
Use wheels with bead locks on the rims if the main
use is going to be on sloping ground. This prevents
tyre run-off on side slopes.
Maximum towed weight
Follow the advice given by manufacturers on the
maximum trailed weight. This will be found on the
equipment or in the instruction handbook.
Note: Universal road going trailers will normally have
the maximum gross weight stated on a separate
notice.
Selecting and using equipment for All
Terrain Vehicles (ATVs)
HSE information sheet

3
Mounted Equipment
ATVs using mounted equipment are safer if the
equipment has:
A low centre of gravity. This improves stability;
A gross weight within the limits the limits approved
by the ATV manufacturer;
No dangerous projections to enquire the operator or
bystanders;
No forward projections which stop head protection
being worn;
Controls which are easy to work and which do not
create a hazard to the operator;
Working speeds less than 16hp.
Instructions for the mounted and trailed
equipment
Take note of the manufacturers instructions on:
Operating on slopes;
Where to place loads so as to give fore/aft and
lateral stability;
The risks of using equipment with negative drawbar
nose weight, i.e. loss of traction;
The maximum operating speed;
The effect that equipment carried on front and/or
rear racks will have on longitudinal and lateral
stability;
Securing loads;
The use of ballast, if any to improve stability;
The need to select and use safe routes.
Using an ATV
Read the manufactures instruction book and take
note of the safety advice given;
Choose an ATV with enough power for the work you
want it to do. Four wheel drive will give better
traction and mobility and may provide a margin of
safety;
Choose a safe route;
Be aware that increased speed greatly increases the
risk of instability and the risk of an overturn.
Printed and published by HSE
Training
Train everyone who has to use an ATV whether with
mounted or trailed equipment or as a solo machine.
The training should emphasise the factors affecting
stability, the need for care and concentration, and
how to recognise the conditions, which may affect
the safety of operation. It is important for trainees to
familiarise themselves with the handling and control
of the machine on level open ground before tackling
rough hill terrain.
Suitable training courses are run by such bodies as
ATB Landbase and Forestry Authority.
Helmets
Wear head protection, which protects the head and
neck. Helmets to BS 6658:1985 (specification for
protective helmets for vehicle users) are suitable.
Some users find open faced helmets more suitable
than full face helmets.
Use of ATV’s for Spraying
A separate information sheet No 10 ATV’s fitted with
spray equipment is available from the Crop and
Pesticides National Interest Group (see address
below)to cover the use of mounted or trailed ATV
sprayers.

6.1 – BEFORE USE CHECK THE FOLLOWING:
1. Ensure the tow ball on the vehicle is compatible with the spreader.
2. Check the operation of all controls (A).
3. Ensure the ride height is correctly set for the ATV towing the spreader (B). Remove the
fixing bolt and adjust the angle of the spreader to ensure the spreader disc is running
horizontal to the ground. Replace the fixing bolt in the nearest hole available. (The
spreader disc must run horizontally to the ground to ensure the correct spreading width
and overlap is achieved)
4. Check that the tyre pressure (C) 10psi minimum to 25psi maximum dependant on load
size. Check the condition of the tyres. Look for signs of wear, cuts and impact damage.
5. Check the free operation for the shutter aperture (D).
6. Check the condition of the hopper and lid (E, If fitted).
7. Check that all grease points have been greased, and are operating freely.
8. Check the gearbox for oil leaks, if an oil leak is evident do not use the spreader and carry
out repairs immediately.
Check that the agitator (G) is free from debris and well greased.
9. Before filling the hopper, set the flow from the hopper by moving the pointer (A) to the
setting required (B) and locking in place with the lock nut (C).See figure 11.1

10. Place the flow lever (D) in the zero position and fill the hopper with the material to be
spread. Ensure that a suitable towing vehicle has been hooked up to the spreader before
filling and that the handbrake has been applied. Do not overfill the hopper; this could
result in fertilizer being spilt or component failure. Ensure there are no foreign bodies in
the hopper e.g. stones or rocks. Wear suitable protective clothing and face protection.
11. Drive to the area requiring the fertiliser, move the drive lever (E) to the IN position (F)
gently moving forward at the same time.
Figure 11.1
6.2 – DISTRIBUTION OF THE FERTILISER/SALT:
The operator must ensure that the towing vehicle travels at a constant speed in order to obtain
an even distribution of material, the operator should use the following overlap technique as
illustrated below:

6.3 – VANE REGULATION / ADJUSTMENT:
Should the distribution prove to be uneven, the operator can remedy this by regulating the angle
of all the vanes by adjusting the vanes to the different holes on the spreader disc.
6.4 – CALIBRATION (FERTILISER)
To precisely calibrate the spreader carefully read and perform the following instructions:
1. Place a measured amount of fertiliser in the hopper e.g. 10kg
2. Choose an aperture setting to suit the rate required for the type of fertiliser being used,
e.g. Setting 6
3. Obtain the desired travel speed (12 to 20kpH) and open the aperture to preset setting 6,
e.g. 200 metres. (NOTE: Maintain a constant speed)
4. Check the effective spread coverage width, e.g. 12 metres (D).
5. Measure the amount of fertiliser left in the hopper, e.g. 4kg (E).
Then perform the following calculations: -
Measured amount of fertiliser initially loaded in hopper (A): 10kg
Deduct any remaining fertiliser (e): 4kg
Balance used (B): 6kg
Multiply width of spread (D) by the metres travelled (C): 12 x 200 Mtr = 2400 Mtr²
Divide 10,000 (1hectare) by the answer (2,400): 10,000
2400 = 4.1
Multiply the sum (4.1) by the test quantity balance used (B, 6Kg): 4.1 x 6 = 24.6 kg/Ha
The figure achieved is the sowing rate per hectare at the constant speed selected for the test.
Due to the variations of seeds and fertiliser types, it is recommended the test be carried out for
each product being used. Adjust the machine accordingly until the desired application rate is
achieved.
Record all results to ensure accurate speed rates for future reference, use the chart provided on
page 13).

6.6 - LDS120DS – CALIBRATION (SALT)
The Logic LDS120DS is capable of spreading dry white bagged de-icing salt only.
All materials will vary slightly, depending on density and moisture, etc, even in bags, the same
batch can vary.
The following steps are intended as a guide only, and it is highly recommended that simple test
runs are carried out in the filling area before setting out, to check that the spreading quantity
and pattern are satisfactory.
The main controlling factor is forward speed, which dictates the spreading width. The
application rate will then be controlled by the feed gate setting.
The recommended minimum working forward speed is 3 mph (5 kph). This would be used in
confined spaces, or where a minimum spreading width is required. At this speed the spreading
width will be approx. 8mtrs. Recommended maximum working speed is 12 mph (19 kph)
which will result in a spreading width of approx 12mtrs suitable for car parks and roads, etc.
The feed gate setting at the front of the hopper controls the material flow and therefore the
application rate (grams per sq metre). Our recommendation would be to use setting 6 for
spreading salt; the aperture needs to be open enough to prevent the salt bridging in the hopper.
For transporting max / min operating speeds see page 4.
CALIBRATION STAGES
1. Decide what spread width is required in relation to a safe working speed.
2. Select the feed gate setting to achieve the desired application rate.
This will depend on trials carried out with materials to be spread at the time.
3. Check the accuracy of the settings, try a few trial runs over a clean area of concrete or
road surface, at the correct forward speed. Check the spread width, which may vary due
to bouncing material if it is very dry.
Check the application rate by visually looking at your test run and ensure a suitable
amount of salt is spread evenly. To change the application rate alter the forward speed
or aperture setting accordingly to ensure the correct amount of salt you require is applied
4. Write down results for future reference in the table provided (See next page).

Always empty the hopper before any maintenance is carried out
7.1 - DAILY
1. Check the condition of the engagement mechanism and grease daily. Use the following
procedure, firstly engage the drive, and then pump grease into the nipple.
2. Check the condition of the spreader, if any parts need replacing this should be carried
out before operating the machine.
3. Check tyre pressures before use.
4. Check all nuts and bolts are secure before operating.
5. Check the condition of the swivel hitch bushes and replace if damaged or worn
excessively.
6. Check the tension on drive chain and lubricate when necessary (LDS700 Only)
7. Always wash the spreader thoroughly after use, spray a CORROSION INHIBITOR over
the spreader disc and axle components to prevent corrosion. (LDS120DS version, see parts
list)

7.2 - SEASONAL
1. Check the condition of the drive engagement lever and the plastic tube liner.
2. Check the wheel bearings for play and pack with grease every six months
3. Open the aperture and clean around the aperture blades and holes.
4. Periodically remove the agitator by removing the retaining pin located under the hopper.
5. Lift the agitator, clear of the shaft and remove any residue. Grease and replace the
agitator. Ensure the retaining pin is re-fitted and held in place by the spring clip.
6. Check the oil level in the gearbox. To check, turn the spreader on its side, remove the
filler plug located in the base, check that the oil is level with the rim of the hole, top up if
necessary.
Change the gearbox oil (EP 90) every six months with normal use, or every three months
under extreme conditions. The quantity of oil required is 300ml.
Maintenance should be undertaken regularly, good maintenance extends the
life of the spreader.
